Harvey Tool 882324-C6 Corner Radius End Mill 3/8in 7 Flute

Product Description

The HARVEY TOOL 882324-C6 is a solid carbide corner radius end mill designed for high-performance material removal in hardened steels ranging from 45 to 68 Rc. It features a 3/8-inch mill diameter, a 1-1/8-inch length of cut, and a 1/64-inch (0.0150-inch) corner radius that reduces stress concentrations at the cutting edge. The 7-flute, right-hand helical geometry supports both roughing and finishing operations in a single pass. An AlTiN PVD coating provides thermal resistance and extends tool life in demanding cutting environments. This end mill is intended for use in CNC machining centers with high-precision toolholders.

This end mill is built for machining hardened steels, stainless steel, cast iron, and hard alloys, making it well-suited for die and mold work, aerospace components, and precision tooling applications where tight tolerances and surface finish are critical. The variable helix design reduces harmonic chatter, which is especially important at elevated cutting depths in hardened materials. It is a single-end tool with a straight cylindrical shank and is sized for setups where a 3/8-inch shank diameter fits the toolholder specification. It is typically installed and operated by machinists and CNC programmers working in job shops or production machining environments.

Key Features

• 7-flute geometry supports both roughing and finishing in hardened steels 45-68 Rc
• Variable helix reduces chatter and improves surface finish at depth
• AlTiN PVD coating provides thermal and wear resistance in high-hardness materials
• 1/64-inch corner radius (0.0150 inches) with a tight tolerance of plus or minus 0.0010 inches
• Close pitch flute spacing maximizes chip room while maintaining edge strength
• Solid carbide construction for rigidity and dimensional stability

Compatibility

Designed for use with high-precision toolholders. Primary workpiece materials include steel, stainless steel, cast iron, and hard alloys. Part of the HARVEY TOOL End Mills for Hardened Steels - Corner Radius series, rated for steels at 45-68 Rc.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with CNC milling setups. Secure the shank in a high-precision toolholder to the toolholder manufacturer's specified clamping procedure before initiating any cutting cycle. Verify spindle runout is within acceptable limits prior to engaging the workpiece, as excess runout accelerates edge wear on multi-flute carbide tooling. Follow the cutting tool manufacturer's recommended speeds and feeds for the specific workpiece hardness and material grade.
